Low Power Operation Benefits
The “L1” designation in XCZU7CG-L1FFVC1156I indicates this device is specifically screened for lower maximum static power consumption. When operated at VCCINT = 0.85V, the device maintains the same speed specifications as standard -1I speed grade devices. Operating at VCCINT = 0.72V further reduces both performance and static/dynamic power, enabling ultra-low-power designs for battery-operated or thermally constrained applications.
